ABSTRACT:
A method and apparatus receive, detect, collect and analyze program-identifying (“PI”) information contained in a plurality of broadcast or recorded electronic audio signals. Each audio signal represents the sounds (audio portion) in a plurality of sequential program segments, such as program material or commercials. The method comprises the steps of receiving a selected one of the audio signals at each of a plurality of remote locations; reproducing the sounds represented by the selected audio signal at each remote location; converting the sounds into a second electronic signal at each remote location; detecting the PI information from the second signal at each remote location; storing the detected PI information at each remote location; establishing a wireless communication link between each remote location and a central computer at another location and transmitting the PI information to the central computer; storing the PI information received from the plurality of remote locations at the aforesaid central computer; and analyzing the stored PI information to obtain a statistical estimate of the relative number of persons who listened to the sounds in each given program segment.
